How to find sum of squares

Identify the first and last terms in the sequence. You need to know both of these numbers in order to calculate the sum of the arithmetic sequence. Often the first numbers will be 1, but not always. Let the variable equal the first term in the sequence, and equal the last term in the sequence.
